System Operational Checks
The following procedure will confirm that the RF interface cables between the Test
Set and analyzer are installed and the system is working correctly. Ensure that your
analyzer is calibrated by measuring the short on each port before connecting the Test Set.
Before beginning this procedure complete the following steps:
•
Stack the analyzer on top of the Test Set.
•
Install the Test Set I/O cable on the rear panel.
•
Install all of the RF interface cables on the front panel.
•
Install the included female 3.5 mm short (85052-60007) to Port 1 on the analyzer.
Equipment Setup
•
Turn on the test set and analyzer.
•
Preset the analyzer and make the following settings:
— Set to Multi-Port Mode
— Frequency range: 10 MHz to 26.5 GHz
— IFBW:
1
kHz
— Scale:
10
dB/Div
— Set the PNA to measure S11
—
Ensure the RF path of the analyzer is in Default mode. Refer to
Configuration with Analyzer Option 029” on page 3

The 3.5 mm short will be relocated to each Test Port and an uncorrected reflection
response trace should be displayed that resembles the following plots indicated in
the table below. If you suspect an RF signal path problem, refer to the RF cable
diagram and check the interface cables associated with this signal path for proper
installation.
